Furina will receive a bag of macarons of different colors, assorted cookies of different flavors, and a whale plushie. There's no name attached to the gifts, but there is a note that says:

All the world's a stage, and you are its finest actor. Now that you are freed from the character you had to perform as for so long, I hope you can find who you are and love yourself again. I'm cheering for you!
